ABSTRACT

A heating control device for controlling a food processor is disclosed. During a heating process of the food processor, a temperature in a cup of the food processor is obtained at a predefined time interval. Whenever the obtained temperature in the cup reaches a current preset temperature threshold, the food processor starts a stirring operation for a first preset time period and stops after that, until the obtained temperature in the cup is greater than an upper limit of the preset temperature threshold. The preset temperature threshold is adjusted and defined as the current preset temperature threshold every time before the food processor starts the stirring operation. The heating control device for controlling the food processor solves a problem of a low accuracy in heating control that is caused by an unbalanced temperature in the cup of the food processor during the heating process.

BACKGROUND

A blender with heating function is a new type of food processor, heatingand stirring operation are provided simultaneously so that the foodprocessing functions such as cooking porridge, rice paste and soybeanmilk that need to be heated can be accomplished. However, during theheating process, due to the position of a heater, as well as theaccumulations of food in the stirring cup, the temperature in the cup isuneven and unbalanced, the temperature is higher at the regions that arenear the heater, while the temperature is lower at the regions that arefar away from the heater. If the temperature detecting device isinstalled near the region of the heater, when the temperature detectedby the temperature detecting device is a predetermined temperature T,the food temperature in the regions far away from the heater is farbelow the temperature T; if the temperature detecting device isinstalled far away from the regions of the heater, when the temperaturedetected by the temperature detecting device is T, the food temperaturein the regions near the heater may be far higher than T; thus thetemperature in the cup is unbalanced, a local temperature would be veryhigh while the other regions are at lower temperature, so the detectedtemperature by the temperature detecting device is not in conformitywith the real temperature, resulting in the low accuracy of heatingcontrol of the blender and damaging the process of cooking the food.

DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be understood that the specific embodiments described beloware only used to explain the present disclosure and are not intended tolimit the present disclosure.

The present disclosure relates to a heating control method forcontrolling food processor. With reference to FIG. 1, FIG. 1 is a flowdiagram of a heating control method for controlling a food processor ina first embodiment of the present disclosure.

In the present embodiment, the heating control method for controllingthe food processor includes:

step S10, during a heating process of the food processor, obtaining thetemperature in the cup, that is detected by the temperature detectingdevice of the food processor, at the regular time.

It should to be note that, the heating control method for controllingthe food processor of the present disclosure can be applied to the foodprocessor with a heating and a stirring operation, such as soybean milkmachines, juicers, grinding machines etc.

For a general food processor, a heating device is provided on a bottomof a stirring cup, during the heating process, with an operation of theheating device, the food temperature in the cup increases gradually fromthe bottom to a top. However, the temperature detecting device isusually provided on the regions that are near the heating device, or isprovided on the regions that are far away from the heating device;therefore, the detected temperature by the temperature detector is notequal to the actual average temperature in the cup, when the foodprocessor starts the heating control, usually taking the temperaturethat is detected by the temperature detecting device as one of judgmentbases. For instance, detecting a boiling of food in the cup, when thedetected temperature by the temperature detector reaches the presetboiling point, then the food in the cup is considered to be boiled andthe food processor is controlled to run a next operational phase.However, if the temperature detecting device is installed on regionsthat are close to the heating device, the temperature of the regionswhich is detected by the temperature detecting device has reached theboiling point, but the food temperature in the regions that are far awayfrom the heating device, has not reached the boiling point yet. That is,at this moment the food in the cup does not actually reach the boilingpoint, which results in a miscarriage of justice to the heating state ofthe food processor for food, and which leads to a low accuracy ofheating control.

The method in the present embodiment, during the heating process of thefood processor, in real time or regularly detecting the temperature inthe cup of the food processor, for example, to obtain the temperaturedetected by the temperature detecting device that is provided in thefood processor at 2 to 5 seconds per interval. In another embodiment,the time interval of regularly detecting the temperature in the cup canbe set greater than the first preset time.

Step S20, in accordance with a determination that the obtainedtemperature in the cup reaches a current preset temperature threshold,controlling the food processor to start the stirring operation and tostop after the first preset time, until the obtained temperature in thecup is greater than an upper limit of the preset temperature threshold;

step S30, adjusting the preset temperature threshold before the foodprocessor starts the stirring operation, and the adjusted presettemperature being defined as the current preset temperature threshold,the adjusted preset temperature threshold is greater than or equal to aprevious preset temperature threshold.

When the temperature detected by the temperature detecting device in thecup is obtained, comparing the obtained temperature in the cup with thepreset temperature threshold, if the temperature in the cup is greaterthan the current preset temperature threshold, and then the stirringoperation is started then stopped after the first preset time, todecrease the temperature of the regions that are near the heating deviceand to increase the temperature on the regions that are far away fromthe heating device, thus making the overall temperature reach anequilibrium in the cup, thereinto, the first preset time is set up byusers according to the actual needs, such as 10 to 30 seconds etc.Furthermore, with the effect of the heating device, the temperature inthe cup may increase again, therefore adjust the preset temperaturethreshold after the stirring is finished, let the adjusted temperaturethreshold be greater than or equal to the preset temperature threshold.And the adjusted temperature is defined as the current presettemperature threshold. If the detected temperature is greater than thecurrent preset temperature threshold once again, then start the stirringoperation to stir the food, recurrently, until the detected temperatureby the temperature detecting device is greater than an upper limit valueof the preset temperature threshold.

The adjustment of the preset temperature value may have variousembodiments and two of them are listed below, in one embodiment, thepreset temperature threshold is adjusted according to the second presettemperature difference, and then defining the adjusted presettemperature as the current preset temperature threshold. Optionally, aninitial value of the preset temperature threshold is set to be greaterthan or equal to 40° C., the upper limit value is less than or equal to95° C. Controlling a frequency of starting the stirring operation of thefood processor to be less than 20 times. The first preset temperaturedifference is determined according to the initial value of the presettemperature threshold, the upper limit value of the preset temperatureand the frequency of starting the stirring operation. The presettemperature threshold is adjusted repeatedly to reach the upper limitvalue of the preset temperature threshold, while the total times cannotexceed 20. For example, the initial value of the preset temperaturethreshold is 50° C., the first preset temperature difference is 5° C.,the upper limit value of the preset temperature threshold is 95° C.,thus adjusting the preset temperature threshold to 55° C. after stirringby the first time, adjusting the preset temperature threshold to 60° C.,and so on, until the detected temperature in the cup is greater than theupper limit value of the preset temperature threshold.

Here is a specific usage scenario to illustrate the heating controlmethod for controlling the food processor proposed by this method.Taking the temperature detecting device provided in the regions that arenear the heating device as an example, thereinto, the initial value ofthe preset temperature value is 50° C., the first preset temperaturedifference is 5° C., a first preset time period is 20 seconds, the upperlimit value is 95° C. In the present embodiment, the preset temperaturemay be 50° C., 55° C., 60° C., 65° C., 70° C., 75° C., 80° C., 85° C.,90° C., and 95° C., successively.

During the heating process of the food processor, the detectedtemperature in the cup is obtained in real-time by the temperaturedetecting device; when the detected temperature in the cup reaches to50° C., then the food processor is controlled to start the stirringoperation and to stop after stirring for 20 seconds, the presettemperature value is increased by 5° C. and defined as the currentpreset temperature threshold, that is 55° C. After stirring, thetemperature in the cup may reduce to under 50° C., such as 48° C.,because the heating device is still heating, so the temperature in thecup will increase gradually. When the detected temperature in the cupreaches to 55° C., start the stirring operation again and stop afterstirring for 20 seconds, and the preset temperature value is increasedby 5° C. and defined as the current preset temperature threshold, thatis 60° C. After stirring, the temperature in the cup may reduce to under55° C., such as 53° C., because the heating device is still heating, sothe temperature in the cup will gradually increase; when the temperaturein the cup is reached 60° C., to start the stirring operation again,recurrently, until the detected temperature in the cup is reached theupper limit value of the preset temperature threshold of 95° C., thenstopped stirring. Preferably, in one embodiment, the initial value ofthe preset temperature threshold may be set as 75 to 85° C., the firstpreset temperature difference is 1 to 3° C.

Thereinto, for judging whether the temperature in the cup reaches thecurrent preset temperature threshold or not, when the detectedtemperature in the cup is greater than or equal to the current presettemperature threshold and then the temperature in the cup is consideredto reach the current preset temperature threshold.

With reference to FIG. 2, in other embodiments, adjusting the presettemperature threshold, a process of wherein the preset temperaturethreshold is adjusted each time the food processor starts the stirringoperation, and defining the adjusted preset temperature as the currentpreset temperature threshold, includes the following detailed steps:

step S31, obtaining the second temperature difference corresponded tothe preset temperature threshold, the greater the preset temperaturethreshold, the greater the corresponding second temperature difference;

step S32, the preset temperature threshold is adjusted according to thesecond preset temperature difference, defining the adjusted presettemperature as the current preset temperature threshold.

With the heating process and the intermittently start of the stirringoperation, making an overall temperature in the cup tend balancegradually. In the present embodiment, a second preset temperaturedifference is provided to correspond with every preset temperaturethreshold, with the increase of the preset temperature threshold, thesecond temperature difference also increases gradually.

Below is another specific usage scenario to illustrate the heatingcontrol method for controlling the food processor that is proposed inthe present embodiment. Taking the temperature detecting device providedin the regions that are near the heating device as the example,thereinto, the first preset time is 20 seconds, the initial value of thepreset temperature threshold is 50° C., and the corresponding secondpreset temperature difference is set to 5° C.; after adjusted for thefirst preset time, the preset temperature threshold is adjusted to 55°C., and the corresponding second preset temperature difference is set to7° C.; after adjusted for a second preset time, the preset temperaturethreshold is adjusted to 62° C., and the corresponding second presettemperature difference is set to 9° C., and so on; thereinto, the secondpreset temperature difference needs to set previously, that is, in thepresent embodiment, the preset temperature threshold is increased stepby step. The upper limit value of the preset temperature is 95° C. Inthe present embodiment, the preset temperature may be 50° C., 55° C.,62° C., 71° C., 82° C. and 95° C., successively.

During the heating process of the food processor, the detectedtemperature in the cup is obtained in real-time by the temperaturedetecting device, when the detected temperature in the cup reaches to50° C., controlling the food processor to start the stirring operationagain and to stop after 20 seconds, the preset temperature is increasedby 5° C. and is defined as the current preset temperature threshold,that is 55° C.; after stirring, the temperature in the cup may bereduced to below 50° C., such as 48° C., owing to the heating device isstill heating, so the temperature in the cup may gradually increase;when the temperature in the cup reaches to 55° C., controlling the foodprocessor to start the stirring operation again and to stop after 20seconds, the preset temperature is increased by 7° C. and is defined asthe current preset temperature threshold, that is 62° C.; afterstirring, the temperature in the cup may reduce to below 55° C., such as53° C., owing to the heating device is still heating, so the temperaturein the cup will gradually increase; when the temperature in the cupreaches 62° C., to start the stirring operation again, recurrently,until the detected temperature in the cup is reached to the upper limitvalue of the preset temperature threshold of 95° C., then stop stirring.

In other embodiments, the adjusted preset temperature threshold may beequal to the prior preset temperature threshold by adjusting the presettemperature threshold within one or two times, such as, the presettemperature threshold is 50° C., 55° C., 60° C., 60° C., 65° C., 70° C.,70° C., 75° C., 80° C., 85° C., 90° C. and 95° C., successively. Thespecific control process is basically the same with the foregoingembodiments, and no more details are given here.

It is understandable that, in some embodiments, the temperaturedetecting device may provide on the regions that are far away from theheating device, therefore, the temperature in the cup may increase afterstirring, in these embodiments, the time interval of regularly detectingthe temperature in the cup may set to be greater than the first presettime, to improve the accuracy of the heating control.

It is understandable that, in an embodiment, even though the stirringoperation is on, the heating device of the food processor keeps heating,in this way, to improve the heat efficiency and reduce the heating time,making the temperature in the cup reach the preset temperature as soonas possible; in other embodiments, the heating may be suspended evenwhen the stirring operation of the food processor is on, and the heatingis continued when the stirring is finished, in this way, to reduce thestirring time, which is the first preset time, thus realizing a rapidequilibrium of the overall temperature in the cup. Specifically, duringthe heating process of the food processor, if the stirring operation isdetected on working, then to suspend the food processor from heating. Ifthe stirring operation of the food processor is detected with stoppingwork, then the food processor is controlled to heat continually.

It should be note that, the temperature value listed in the foregoingembodiment is just to give an illustration, the present disclosure isnot limit to this, thereinto, relevant parameters of the food processor,such as the first preset time, the first preset temperature difference,the second preset temperature difference etc., may be set before leavingfactory, for example, a better value may be obtained from the simulationexperiment.

Furthermore, the boiling point of the food may be used as the upperlimit value of the preset temperature threshold.

The present embodiment relates to the heating control method forcontrolling the food processor, regularly detecting the temperature inthe cup during the heating process of the food processor. Whenever theobtained temperature in the cup is greater than the current presettemperature threshold, then the food processor is controlled to startthe stirring operation and to stop after the first preset time, thetemperature in the cup is equalized by stirring until the detectedtemperature in the cup is greater than the upper limit value of thepreset temperature threshold, adjusting the preset temperature thresholdevery time before the food processor starts a stirring operation. Theadjusted preset temperature threshold is greater than or equal to theprevious preset temperature threshold, and defining the adjusted presettemperature as the current preset temperature threshold. That is, duringthe heating process, according to the detected temperature in the cup tostart the stirring operation at intervals to balance the temperature inthe cup. When the stirring operation is started, the preset temperaturethreshold is adjusted, and then the adjusted preset temperaturethreshold is defined as the current temperature threshold, using as thejudgment basis for starting the next stirring, until the detectedtemperature in the cup is greater than the upper limit value of thepreset temperature. The method of the present disclosure avoids asituation of that a local temperature in the cup is high while otherregions are in low temperature during the heating process, thetemperature of the cup is balanced by intermittent stirring and theaccuracy of heating control of the food processor is improved.

A second embodiment of the heating control method of the presentdisclosure is proposed based on the first embodiment. The heatingcontrol method of controlling the food processor further includes thefollowing steps:

after determining that the detected temperature in the cup is greaterthan the upper limit value of the preset temperature threshold,controlling the food processor to continue heating and to stop after thesecond preset time.

When the temperature in the cup reaches the upper limit value of thepreset temperature threshold, the overall temperature in the cup of thefood processor is high and may even have reached the boiling point;thereinto, the food needs to continue heating for a certain time andkeeps boiling for a period time, thus the food is cooked. Therefore, inthe present embodiment, when the detected temperature in the cup isgreater than the preset temperature threshold, controlling the foodprocessor to continue heating and to stop after the second preset time;thereinto, different food needs different heating time, so the foodinformation may be obtained from cooking patterns that are selected byusers. And then, according to the food information, the second presettime is set. In other embodiments, based on the cooking mode that isselected by the users, after determining that the detected temperaturein the cup is greater than the upper limit value of the presettemperature threshold, the food processor executing a follow workflow iscontrolled according to a cooking curve of the cooking mode.

The present disclosure also relates to a heating control device forcontrolling the food processor.

With reference to FIG. 3, FIG. 3 is a block diagram of the heatingcontrol method for controlling the food processor in the firstembodiment of the present disclosure.

In this embodiment, the heating control device for controlling the foodprocessor includes:

a temperature acquisition module 10, configured to obtain thetemperature in a container that detected by a temperature detectingdevice of the food processor at the regular time, during the heatingprocess of the food processor.

It should be noted that the heating control method for controlling thefood processor of the present disclosure may be applied to the foodprocessor with heating and stirring operation, such as soybean milkmachine, juicer, grinding machine etc.

For a general food processor, the heating device is provided on a bottomof the stirring cup, during the heating process, with the operation ofthe heating device, the food temperature in the cup increases graduallyfrom the bottom to the top. However, the temperature detecting device isusually provided on the regions that are near the heating device, orprovided on the regions that are far away from the heating device.Therefore, the temperature detected by the temperature detector is notequal to the actual average temperature in the cup, when the foodprocessor carries out the heating control process, usually takes thedetected temperature of the temperature detecting device as one of thejudgment bases. For example, for detecting a boiling of food in the cup,when the detected temperature of the temperature detector reaches thepreset boiling point, then the food in the cup is considered to havebeen boiled with consequently controlling the food processor to work ina next operational phase. However, if the temperature detecting deviceis installed on the regions that are close to the heating device, thetemperature of the regions that are detected by the temperaturedetecting device has reached to the boiling point, but the foodtemperature of the regions that are far away from the heating device hasnot reached to the boiling point yet, this moment the food in the cuphas not actually reached to the boiling point, resulting in amiscarriage of justice to the heating state of the food processor forfood, which causes a low accuracy of the heating control.

During the heating process of the food processor, the temperatureacquisition module detects the temperature inside the cup of the foodprocessor in real time or timing, for example, the temperature that isdetected by the temperature detecting device, is obtained by thetemperature acquisition module 10, at 2 to 5 seconds per interval, andthe temperature detecting device is provided in the food processor. Inanother embodiment, the time interval of timing obtains the temperaturein the cup may be set greater than the first preset time.

A stirring control module 20 is configured for when the obtainedtemperature in the cup reaches the current preset temperature threshold,controlling the food processor to start the stirring operation and tostop after the first preset time, until the obtained temperature in thecup is greater than the upper limit of the preset temperature threshold;

A threshold adjustment module 30 is configured to adjust the presettemperature threshold each time before the food processor starts thestirring operation, and the adjusted preset temperature being defined asthe current preset temperature threshold, the adjusted presettemperature threshold is greater than or equal to the previous presettemperature threshold.

When the temperature detected by the temperature detecting device in thecup is obtained, comparing the obtained temperature in the cup with thepreset temperature threshold. If the temperature in the cup is greaterthan the current preset temperature threshold, then start the stirringoperation and stop stirring after the first preset time so as todecrease the temperature on the regions that are near the heating deviceand to increase the temperature on the regions that are far away fromthe heating device, which makes the overall temperature reachesequilibrium in the cup. Thereinto, the first preset time is set up bythe users according to the actual needs, such as 10 to 30 seconds etc.Furthermore, with the effect of the heating device, the temperature inthe cup will increase again, therefore, adjusting the preset temperaturethreshold after the stirring is finished and letting the adjustedtemperature threshold greater than or equal to the preset temperaturethreshold, and defining the adjusted temperature as the current presettemperature threshold. If the detected temperature is greater than thecurrent preset temperature threshold once again, then start the stirringoperation to stir the food, recurrently, until the detected temperatureof the temperature detecting device is greater than the upper limitvalue of the preset temperature threshold.

The adjustment of the preset temperature threshold may have variousembodiments and two of them are listed below, in one embodiment, thepreset temperature threshold is adjusted according to the second presettemperature difference, and then defining the adjusted presettemperature as the current preset temperature threshold. Optionally, theinitial value of the preset temperature threshold is set to be greaterthan or equal to 40° C., the upper limit value is less than or equal to95° C., a total times of starting the stirring operation of the foodprocessor is set to be less than 20 times, the first preset temperaturedifference is determined by the threshold adjustment module, accordingto the initial value of the preset temperature threshold, the upperlimit value of the preset temperature and the frequency of starting thestirring operation. The preset temperature threshold is adjustedrepeatedly to reach the upper limit value of the preset temperaturethreshold, while the total times of adjustment cannot exceed 20. Forexample, the initial value of the preset temperature threshold is 50°C., the first preset temperature difference is 5° C., the upper limitvalue of the preset temperature threshold is 95° C., so that the presettemperature threshold is adjusted to 55° C. by the preset temperaturethreshold after stirring by the first time, and the preset temperaturethreshold is adjusted to 60° C. by the preset temperature thresholdafter stirring by the second time and so on, until the detectedtemperature in the cup is greater than the upper limit value of thepreset temperature threshold.

Here is a specific usage scenario to illustrate the heating controldevice for controlling the food processor proposed by this method.Taking the temperature detecting device as an example, thereinto, theinitial value of the preset temperature threshold is 50° C., the firstpreset temperature difference is 5° C., the first preset time is 20seconds, the upper limit value is 95° C. In the present embodiment, thepreset temperature threshold is 50° C., 55° C., 60° C., 65° C., 70° C.,75° C., 80° C., 85° C., 90° C. and 95° C., successively.

During the heating process of the food processor, the temperatureacquisition module 10 obtains the detected temperature in the cup by thetemperature detecting device in real-time, when the detected temperaturein the cup reaches 50° C., the stirring control module 20 controls thefood processor to start the stirring operation and to stop after 20seconds, increasing the preset temperature by 5° C. and is defined asthe current preset temperature threshold, that is 55° C., afterstirring, the temperature in the cup may reduce to below 50° C., such as48° C. Owing to the heating device is still heating, so the temperaturein the cup will gradually increase. When the temperature in the cupreaches 55° C., starting the stirring operation again, stopping after 20seconds, increasing the preset temperature by 5° C. and then theincreased temperature is defined as the current preset temperaturethreshold, that is 60° C., after stirring, the temperature in the cupmay reduce to under 55° C., such as 53° C. Owing to the heating deviceis still heating, so the temperature in the cup will gradually increase.When the temperature in the cup reaches 62° C., starting the stirringoperation again, recurrently, until the detected temperature in the cupreaches the upper limit value of the preset temperature threshold of 95°C., then stops stirring. Preferably, in some embodiments, the initialvalue of the preset temperature threshold may be set as 75 to 85° C.,the first preset temperature difference is 1 to 3° C.

Thereinto, for judging whether the temperature in the cup reaches thecurrent preset temperature threshold or not, when the detectedtemperature in the cup is greater than or equal to the current presettemperature threshold and then the temperature in the cup is consideredto have reached the current preset temperature threshold.

With reference to FIG. 4, in other embodiments, the threshold adjustmentmodule 30 includes the following detailed units.

The temperature difference acquisition unit 31 is configured to obtainthe second temperature difference corresponded to the preset temperaturethreshold; thereinto, the great the preset temperature threshold is, thegreat the corresponding second temperature is.

A threshold adjustment unit 32, configured to adjust the presettemperature threshold according to the second preset temperaturedifference, defining the adjusted preset temperature as the currentpreset temperature threshold.

With the heating process and the intermittently start of stirringoperation, making the overall temperature in the cup gradually tend tobalance, in the present embodiment, a second preset temperaturedifference is provided to correspond with every preset temperaturethreshold. With the increasing of the preset temperature, the secondtemperature difference also increases gradually.

Here is another specific usage scenario to illustrate the heatingcontrol device for controlling the food processor proposed by thisembodiment. Taking the temperature detecting device provided in theregions that are near the heating device as the example, thereinto, thefirst preset time is 20 seconds, the initial value of the presettemperature threshold is 50° C., and the corresponding second presettemperature difference is set to 5° C.; after adjusting for the firstpreset time, the preset temperature threshold is adjusted to 55° C., thecorresponding second preset temperature difference is set to 7° C.;after adjusted for the second preset time, the preset temperaturethreshold is adjusted to 62° C., the corresponding second presettemperature difference is set to 9° C., and so on; thereinto, the secondpreset temperature difference needs to set previously, that is, in thepresent embodiment, the preset temperature threshold is increased stepby step. The upper limit value of the preset temperature is 95° C. Inthe present embodiment, the preset temperature threshold is 50° C., 55°C., 62° C., 71° C., 82° C. and 95° C., successively.

During the heating process of the food processor, the temperatureacquisition module 10 obtains the detected temperature in the cup by thetemperature detecting device in real-time, when the detected temperaturein the cup reaches 50° C., the stirring control module 20 controls thefood processor to start the stirring operation and to stop after 20seconds, the threshold adjustment module 30 raises the presettemperature by 5° C., and the raised present temperature is defined asthe current preset temperature threshold, that is 55° C., afterstirring, the temperature in the cup may reduce to under 50° C., such as48° C., owing to the heating device is still heating, so the temperaturein the cup will gradually increase. When the temperature in the cupreaches 55° C., starting the stirring operation again, then the foodprocessor stops after 20 seconds, increasing the preset temperature by7° C. and is defined as the current preset temperature threshold, thatis 62° C., after stirring, the temperature in the cup may reduce tounder 55° C., such as 53° C., owing to the heating device is stillheating, so the temperature in the cup will gradually increase. When thetemperature in the cup reaches 62° C., and the stirring operation isstarted again, recurrently, until the detected temperature in the cupreaches the upper limit value of the preset temperature threshold of 95°C., and then the stirring process is stopped.

In other embodiments, the adjusted preset temperature threshold may beequal to the prior preset temperature threshold by adjusting the presettemperature threshold within one or two times, such as, the presettemperature threshold is 50° C., 55° C., 60° C., 60° C., 65° C., 70° C.,70° C., 75° C., 80° C., 85° C., 90° C. and 95° C., successively. Itsspecific control process is basically the same as the foregoingembodiments, and no more details are given here.

It is understandable that, in some embodiments, the temperaturedetecting device may be provided on the regions that are far away fromthe heating device, therefore, the temperature in the cup may increaseafter stirring. In these embodiments, the time interval of obtaining thetemperature in the cup at regular time may be set to greater than thefirst preset time, to improve the accuracy of the heating control.

It is understandable that, in an embodiment, even though the stirringoperation is on, the heating device of the food processor continuesheating. In this way, improving the heating efficiency and reducing theheating time, make the temperature in the cup reach the presettemperature as soon as possible. In other embodiments, the heatingcontrol device for controlling the food processor also includes thefirst control module, during the heating process of the food processor,to suspend the food processor from heating if the stirring operation isdetected on working. If detecting the stirring operation of the foodprocessor stops working, the food processor is controlled to heatcontinually. The heating device of the first control module may besuspended even when the stirring operation of the food processor is on,the heating device of the first control module continues heating whenthe stirring is stopped, in this way, to reduce the stirring time, thatis the first preset time, thus realizing a rapid equilibrium of theoverall temperature in the cup.

It should be note that, the temperature values in the foregoingembodiment are merely listed for illustration, the present disclosure isnot limit to this, thereinto, the relevant parameters, such as the firstpreset time, the first preset temperature difference, the second presettemperature difference etc., can be set before the food processor leavesa factory, for example, an appropriate value can be obtained from thesimulation experiment.

Furthermore, the boiling point of the food may be defined as the upperlimit value of the preset temperature threshold.

The present embodiment relates to the heating control method forcontrolling the food processor, regularly detecting the temperature inthe cup during the heating process of the food processor, whenever theobtained temperature in the cup is greater than the current presettemperature threshold, the food processor is controlled to start thestirring operation and to stop after the first preset time,equilibrating the temperature in the cup by stirring, until thetemperature in the cup is greater than the upper limit value of thepreset temperature threshold, wherein the preset temperature thresholdis adjusted each time the food processor starts the stirring operation,the adjusted preset temperature threshold is greater than or equal tothe previous preset temperature threshold, and defining the adjustedpreset temperature as the current preset temperature threshold, that is,during the heating process, according to the detected temperature in thecup, the stirring operation is started at intervals to balance thetemperature in the cup. When the stirring operation is started, thepreset temperature threshold is adjusted, and the adjusted presettemperature threshold is defined as the current temperature threshold,using as the judgment basis for starting the next stirring until thedetected temperature in the cup is greater than the upper limit value ofthe preset temperature. The device of the present disclosure avoids thesituation that the local temperature in the cup is high while otherregions are in low temperature during the heating process. Thetemperature in the cup is balanced by intermittently stirring, so as toimprove the accuracy of heating control of the food processor.

A second embodiment of the heating control device of the presentdisclosure is proposed based on the first embodiment. With reference toFIG. 5, the heating control device for controlling the food processorfurther includes.

A second control module 40 is configured for after determining that thedetected temperature in the cup is greater than the upper limit value ofthe preset temperature threshold, controlling the food processor tocontinue heating and to stop after the second preset time.

When the temperature in the cup reaches the upper limit value of thepreset temperature threshold, the overall temperature in the cup of thefood processor is high and may even have reached the boiling point;thereinto, the food needs to continue heating for a certain time andkeeps boiling for a period time, thus cooking the food thoroughly;therefore, in the present embodiment, after determining that thedetected temperature in the cup is greater than the upper limit value ofthe preset temperature threshold, and the food processor is controlledby the second control module 40 to continue heating and to stop afterthe second preset time; thereinto, different food needs differentheating time, so the food information may be obtained from the cookingpatterns that may be selected by the users, and the second preset timeis determined according to the food information. In other embodiments,based on the cooking mode that is selected by the users, afterdetermining that the detected temperature in the cup is greater than theupper limit value of the preset temperature threshold, the foodprocessor is controlled to execute a following workflow according to acooking curve of the cooking mode.
